This is not as easy as a yes or no question, as you have variables inside and outside.
1. Outside. You cannot "split" the signal. This does not mean you cannot have 2 different destinations (LR & BR). It means you can only have one at a time. You can insert an COAX A/B switch which would allow you to choose either A (=LR) or B (=BR) but not both. A single LNB, as is in the Tailgater, wont know what to do if you try to use two destination receivers, at the same time. The A/B switch will require you to have a receiver at each destination (LR/BR). You can also do this inside, before the receiver, which would require you to run COAX inside, from A/B switch to other destination. Only one receiver can control the dish at a time, Period.
2. Inside. This is what others are mostly talking about. TechWriter has some great links. Run the COAX to your receiver (211k/z). If you have the 211k, you can connect two TVs (one SD and one HD). If you have a 211z or you want to split the HDMI out, you need a
1 x 2 HDMI splitter. This allows you to use 1 receiver on 2 TVs. It is still coming from one receiver. You can still only get one channel at a time. It will be the same channel on both TVs.
Have fun.
p.s If you have ARC or other features in a TV or home theater, pick your HDMI splitter carefully. Splitter do not always support all features.
